Can you spot any of the youngsters in this photograph taken at St John's School?
Chestnut Avenue resident Ron Owen, whose son Michael is at the front on the right-hand side, lent this intriguing snapshot of late 1960s school-life to local historian Cyril Hobbins.
Mr Hobbins, another former pupil at St John's, said: "It's an unusual set-up for a school lesson in those days - it must have been a very informal occasion, either just before or after an event. The hall is choc-a-bloc.
"It is also a very candid shot taken without most of the other children realising, yet no one seems to know who most of them are."
